Probate and contentious probate

We aim to ensure an estate is wound up in a proactive, efficient, effective and timely manner.

Our team can support and guide you through the often unfamiliar territory after a death, helping you to obtain the Grant of Probate, administer the estate and explain the roles and responsibilities of executors and administrators to get the estate wound up as quickly and as efficiently as possible.

“The best-laid schemes o’ mice an’ men…” R. Burns

Our experience tells us that will, estate and trust disputes are many and varied and can be highly damaging to family relationships and costly.

With in-depth knowledge advising on the strengths and weaknesses of disputes, our team will help you to identify the key contested areas and determine the right strategy to resolve your dispute to achieve the best outcome for you and your family.

We are committed to resolving disputes and utilising platforms such as mediation and alternative dispute resolution (ADR). However, should litigation become unavoidable, you can be assured our team will advise and support you throughout that period and keep you abreast of costs at all times.

Our head of department and private client partner, James McMullan, is an associate member of The Association of Lifetime Lawyers. James is also a member of the Society of Trust & Estate Practitioners (STEP), whilst trainee solicitor Charlotte Barbaroussis is an affiliate member of STEP. James is also an Association of Contentious Trust and Probate Specialists (ACTAPS) member.

We understand that you may require a more discreet setting or a home visit to provide your instructions. Therefore, we can arrange to meet you in the comfort of your own home or at your care home or hospital in or around Central London. Click here for more information.
